About Until Payday: Budget Tracker
Until Payday answers one question: how much can you still spend before payday? Enter your payday and pay amount, add upcoming bills such as rent and direct debits, and log what you spend. The app subtracts them and shows what’s left as one big number, in the app and in Home Screen and Lock Screen widgets. A new period starts on payday, and your data stays on your iPhone, with no account and no ads.
The release notes for version 1.0.4 say only that it is optimized for iPhone Duo.
